DUST-REDCEOVER FOR CABDING-I/IACHINES.

Specification of Letters Patent.

Patented June 17,1913.

Application filed December 27, 1910, Serial No. 599,359. Renewed May 5, 1913. Serial No. 765,685.

T 0 all whom it may concern:

Be it known that I, HERBERT SMETI-IURST, of 6%. Albert street, Hollinwood, in the county of Lancaster, England, engineer, have invented new and useful Tmprovements in Dust-Removers for Carding-lvlachines, of which the following is a specification.

This invention relates to apparatus for removing dust from cotton and like carding engines during the processes of stripping and grinding the cards, and has for its object to simplify and improve said apparatus so that it shall be more economical to manufacture, less liable to get out of order, and more readily adaptable to suit the various arrangements and dispositions of carding engines to be found in mills.

My invention comprises the improved combinations and arrangements of parts hereinafter described.

Referring to the accompanying sheet of explanatory drawings :Figure 1 is a front elevation partly in section of my improved apparatus, showing the interior of the same, and Fig. 2 an end elevation showing the apparatus in use upon the dofi'er.

The same reference letters in the two views indicate the same parts.

The dust removing device comprises a fan a or the like mounted within a box like cas ing Z) containing a dust separator and collector c. the said casing being adapted to run on wheels (Z along the rear side of the carding engines.

The stripping brush 6 is partly inclosed within a casing or hood f with which the suction pipe 9 of the fan a communicates by way of the flexible pipe h the latter being detachable from the said hood f. A portion of the casing f is hingedly mounted in position so as to allow of the casing being opened for stripping the brush e of the waste collected thereon.

I provide upon the top of the casing b brackets as i for supporting the stripping brush and its casing when they are being moved from one carding machine to another.

F or driving the fan, I employ a rope j which passes over an intermediate pulley 7c and a pulley m on the stripping brush shaft 71. The pulley 0 on the fan shaft is driven from the pulley p on the counter shaft carrying the intermediate pulley 7a. A longer driving rope is employed between the pulleys 7: and at when the brush a is on the cylinder than when it is on the doft'er.

The 'skelton casing Z; within which the fan a and dust separator a are mounted is surrounded at its sides by wire or like perforated grids or frames as 9 upon which canvas or other filtering material is supported on the inner or fan side. One or more-of said grids or frames 9 is hinged to Z) (see Fig. 1) to enable the interior of the casing to be readily accessible for removing the dust separator 0.

To use the apparatus, it is moved into position with the wheel (Z, nearest to the carding engine at the end where the driving rope j is employed, against the bottom of the coiler of the carding machine. By this means the length of the drive between the pulleys 7c and m can be determined. The brush 6 with its hood f is then placed on the cylinder or doifer and connected up by a driving rope m with the cylinder pulley of the machine and with the pulley 7c. The stripping is performed and the dust and waste collected in the bag 0 and also on the filtering screens carried by the grids 0r frames 9.

To remove the waste from the stripping brush, the flexible pipe h is detached from the hood f and the hinged flap upon the latter opened.

After a number of carding machines have been strippec the bag 0 is removed and turned inside out. It is then ready for reuse.

The flexible armored pipe 72. allows of the brush 6 being placed upon the cylinder or the dolfer or upon the brackets 2'.

By the employment of my invent-ion, I obviate the use of exhaustion pipes extending the length of the cardroom, and also of the large number of inlets to such pipes which result in leakage and involve the employment of an exhaustion fan of an unduly large capacity for the work which is accomplished. Further as all the air drawn in through the hood f and pipe 9 is, after filtration, returned to the cardroom, the ventilating, warming and humidifying arrangements of said room will not be interfered with by the installation of my improved dust removing apparatus.
